Hi Mo,
Hey for how long should I cycle a 10 gallon tank that previously had sick fish that died in it. Ihave cleaned the tank throughoy and cleaned the gravel and decorations alike, 75 percent of the gavel is out cus I want to make sure this time is really healthy enviroment for my Betta that's quarintine in a 1 gallon bowl.

Hi,
I have 14 platy fry in my 10 gallon, and it's beginning to get very very crowded. Today I am going to go out and buy a 2.5 Gallon tub and a 25 watt heater . I plan on moving the 5 biggest fry from the 10 gallon to the 2.5 gallon tub today so it's not as crowded in my 10 gallon until they get their new home. All of them are going to a friend's 30 gallon. ;) How many water changes should I do weekly once they are in there? 3, 1 gallon changes? I have a spare 5 filter that came with my 10 gallon (really only good for a 5) spare, should I use that in there?
